the particular details shown. The one illustratedis formed with the uprights a, a, 'top and bottom cross bars, and the top and bottoinfastening pins as at B, B, one or both of the latter' being provided with a hand nut, and pointed sleeve, at B. This frame, as a whole,is indicated by A. The upright a is provided with eyes or bearings a2, a3,

to hold an adjusting rod to be described.

'A vertically adjustable frame or support for the 'cutting apparatus and other parts is indicated by C, C', these being tubular or angular pieces iitted to, and sliding upon the uprights a., a. Eachlms a trunnion socket at c, and the part C has an eye at c, which as a whole is threaded, or is adapted to have secured to it a nut-like part. l

D indicates a threaded rod mounted in the aforesaid bea-rings a? and a3, and passing through and engaging with the threaded partat c. lt has acrank or hand wheel at d, by which it can be readily turned at any time so that' the support C, Cf, can be adjusted up or down longitudinally of the frame A, as required.

The part which immediately carries the cutters is indicated by E. As shown in F 2, 4, and 5, it is made of angle'iron, having the flanges e, e', so as to be light, and yet suii'iciently'strong. It is connected to the column or upright support A by means oi a trunnioned ring F, and a disk or pivot plate G. Thetrunnioned part- F has trunnions f, f, tted in the aforesaid sockets c, c. This ring'supports a rota-ry disk or `pivot plate G, referably by being grooved or formed with) flangesf3 at the edges, so that the part G can be fitted therein. The connection be tween them can be left loose so that more or less rotation of the pivotplat-e G about its longitudinal axis relative to the ring F can be effected at any time; or it can be made rigid with'the ring F bylrawing up tightly the two ends'of the ring F by the screwf, which passes through the lirtrsfl thereon.

The pivot plate G basal central aperture, through which the bar E passes;l and also apertures for the free passage. et a chain used for a purpose to be described. ln order to give a prolonged support for the bar E, and fortlre chains, tubular projections are formed on or secured to thefpart G, as shown in Fig.

4, at H, H, said projections being flared at the ends h.

The cutter carrier E can be fed forward or drawn back .longitudinally bymeans of a 5 threaded feed rod I, and the nut I' mounted on plate G. This rod is mounted in bearings t, i', and carries a bevel wheel I2 adapted to be rotated by hand or by power.

The cutting apparatus, proper, which is shown, is indicated as an entirety by J. It consists of a cutting and driving wheel L mounted between vheads `\or disks M, M', which are supported in bearing bars K, K, bolted to the front end of the carrier E. Each of these bearing bars is formed with an attachment arm Ic, and a forwardly projecting plate-'like ring k', with an aperture k2. The forward part r of each bearing bar is tapered or gradually reduced in thickness, as shown inv Figs. 7, 8, and 9.

The wheel L is formed with sprocket teeth, some narrower as at l, and others broader as at Z', the latter being provided with detachable cutters Z2. Inside of the peripheral parts of the wheel there is a reduced web Z3, and at the center a hub Z4, which at its opposite ends is beveled or tapered inward, as

at Z5, the hub being constructed with a rela- A tively large centrally arranged oil reservoir Z 3@ (see Figs. 7, 8, and 11.)

The tapered'or beveled sockets Zs in the ends of the hub are preferably square in cross section for a ur ose hereinafter' to be described. lTo t is ub, a bushing of brass, or some othersuitable bearing metal is fitted, i preferably formed of two tubes or Aferrules,

',L, each arranged to receive-'one of the ends of the hub. These bushings are preferablytapered, so that when fitted into the 40 bearing bars K their up er and lower sur# faces will be flush with t e upper and lower surfaces 0f the saidbars.

The two heads or disks M, of the cutting apparatus, which arel substantially -similar 1n form, are larranged on opposite sides of the cutter wheel L, and each has a centrally arranged, inwardly extending, ta-

Bering boss m', square in cross section and` aving a cylindrical passageway extending `centrally therethrough. i

In the outer faces of each of the. heads or disks M, M', arevformed grooves m2, m3,inV

tersecting each other at the center of`the disk at right angles. The groove lm2 extends acrossthe face of the disk and has a curved bottom wall m4 lower thanA the bottom wall of the groove m3. The side walls of the groove m are preferably oppositely inclined to its bottom wall, as shown. In these grooves in the disk M are fitted cutters N O, respectively; and inthe corresponding grooves in the disk M',I areiitted similar cutters N', O'.

The cutters N, N', are so shaped on their inner sides as to'permit them to rock across seams planes which are transverse to the axis of the disks which carry them. Each is recessed at n, on each side of the center, and is formed with an enlarged eye or ring n' at the center. The recesses n extend to a radial distance, a little greater than the radius of the periphery of the bushing L'from the axis of the disks, so that the thicker part of the cutter, in fact, the cutting edge proper n3 can move inward past the outer edge of the bottom wall 'm4' of the groove m2 and lie closely adjacent to the outer taperin surface of the adjoining bearing support The bottom wall of the recess n rests upon the bottom wall of the groove m2 andisadapted to rock thereon.

The cutters O, O',are, as said above, fittedl in the grooves m3, and ada ted to be secured rigidly to the heads o r dis s M, M. Each is formed with a tubular boss o, which passes loosely through the eye or ring n' in the adjacent cutter N, N', and is adapted to be fitted snugly in a recess m5 in the bossI m' of the disk which carries it. 'The side edges of the cutters O, O', are preferably inclined to vthe top `and bottom walls of the cutters and are arranged to engage the inclined side walls of the grooves m3.

Thev manner of arranging the parts'above described, and also the manner in which they operate, will be readily understood from the description in connection with the drawings. The wheel L, the cutter heads or ,disks M, M', and the cutters carried thereby after being placed properly in the bearing bars K, are all clamped together by a bolt or screw P, having one end countersunk in the cutter Y O and the other end screwed into the cutv ter O'. l Y, l

e The cutters Z2 in the wheelL act to re'- move the material from the front of the cutting and driving wheel. The cutters 0, O', act similarly to removeall that lies directly in front of the cutter headsM, M.- That which lies in front of the bearing bars K, K, is reduced and removed by the vibrating cutters N, N', since when the cuttin part proper n3 at either end'of'each cutter-1s 'traversing the forward portion of its circle, it ,can move inward and lie in that plane transverse to the axis of rotation in whi'chthe outer portion of the adjacent bar K'lie's, thecutters N, N', at such times lying in alane inclined to the plane of the main or wheel L of the apparatus.` The forward end of each of thecutters N, N'is yat such times, compelled to thus swing or move i'nto the planeof the adjacent bearingibar K, because of the fact that the other, orat that `time rear end, of each of said cutters is movingl over the rear surface of the adjacent inclined plate f', which being at a greater distance from .the longitudinal axis of the machine than is the front surface of the plate, acts as a cam to rock the' cutter in its carrying disk, swinging' its frontcutting edge n3 inward and riving cutter he cutter wheel L 1s rotated by the chain l Q, which extends back to a driving wheel Q',

supported on the part I3, and bar E, it being Aupon a shaft t4. Thisshaf't has a gear wheel 2 with which a pinion r engages, the latter being driven by the armature of an electric motor indicated as a whole bylt, and supported upon the cutter carrier. One strand chain liesabove, or at one side of the carrier E, and theother liesv below it, or on the opposite side. tubular guides H, H, in the adjustable support, and are therein held properly in position in driving relation to the wheels Land Q. Q3 isa gear wheel'mounted on the shaft t4 and adapted to be actuated by the motor and to eng-acre with and rotatethe gear I2. This wheel 3 is preferably rigid with the ear Q2 which is slidingly fitted on the shaft y a spline, so as to rotate therewith, and yet l be capable of longitudinal movement thereon so as to permit gear Q3 to be moved into and' out of'engagement with the pinionI.

It it is desired to feed by hand, a wheel S2 is provided which can be put into engagement with the wheel I2, it being supported on a shaft s mounted wherein it can be moved longitudinally to cause the wheel S2 to engage with, or be disengaged from the gear I2. S is a hand wheel for operating the shaft s.`

The machine which I have shown and above described, can be used either for shearing, that is to say forming a vertical cut, or tor forming a horizontal one,vat the iioor line, that is an undercut, or it can be used to form Aan inclined cut, or to work an excavation aroundmasses of foreign materials,such as sulfur balls. In Fig. it is arranged for shearing or forming a vertical cut. It it is assumedthat an electric current is entering the motor R, and' causing it to actuate the driving parts, it will be seen that the cutting apparatus at J will be rotated by the chain Q, and that the cutter carrier E and the cutter will be advanced by the threaded rod I and nut I. W'hile the cutters are rotating, they can be rocked or vibrated up and down, the trunnioning at permitting such movement. At the same time they are capable of being rocked or vibrated in horizontal planes aboutthe axis of the fastening pins or bars B, B. Therefore avertical cut can be formed in a plane face of the coal. In order to cut a horizontal kerf it is only necessary to loosen the plate 'G by the screw f2. W'hcn the parts of the ring ,F have been 'separated slightly, the plate G and parts connected about the axis of said plate, which extends longitudinally of the apparatus in the direction ofl the length of the shaft I to bring the They pass through they 1nA a suitable bearing therewith can be rocked at any desired angle to the f rangement, and adjustment of the parts,

v z ontallyv y,to cut on lines crossing cutters to the desired plane. After such ady justment, it may be clamped tightly in positicior it may be left loose, so that the cutters can be varied somewhat from. the horizontal plane, as may be' necessary in passing around an obstructionorvin following the curvatures of a slate vein, or layerof sultur. In short, it will be seen that under this arthe cutters and the cutter carrier are capable of universal adjustment.`

It will be noted that the power is applied directly to the cutting and driving wheel L, and that such wheel is so connected with the cutter heads or disks M M", as to rotate them,

-and the cut-ters N, and O, O/ 5 the cutters N, N', operating in planes inclined to the planes of the main wheel Il, as well as to the planes oi the cutters O, O', and being adapted to removeA the coal between the -main wheel L and the cutters O, O.

l is capable of holding a The oil reservoir Y of oil which can comp arativehY large quantity -pass through the ducts o to the outside of the brass bushings which lit in the bearing k bars K, and as the bushings'are comparativoli7 large, a large wearing surface is provided and durability is insured.
